I own a 70-300mm lens which I find it too short for any birdshoot activity
was thinking of some cheaper alternative like add a 1.4x or 2x to this 70-300
sigma lens, anyone have experience with that? some picture posting?

How much is a 300mmL cost? or 50-500?

100-400mm IS is around $2.6+k
300mm IS f4 L is around $2.3+k,
400mm F5.6L is around $2.1+k,
50-500mm SIGMA around $1.6-1.8k

Ah! A bird fan! The bad news is, unless you are willing to shell out a lot of $$$ for super-exotic glass you will be:

1. Pushing the ISO
2. Shooting static birds (unfortunately, birds like resting in the shade!)
3. Shooting moving birds in bright sunlight

Did you say you have a 70-300? If this is a Canon lens, don't you mean 75-300/4.5-5.6? These come in three versions - vanilla, with USM on top, and with USM+IS and cherries on top. The 70-300 is the 4.5-5.6 DO IS (new and very expensive!).

1.4x and 2x extenders are usually not recommended, and would physically not fit your lens. Even if you get a Tamron (which will fit) you will lose autofocus, because the effective aperture is greater than F/5.6.

Cheapest high quality solution is to get either a 400/5.6L or a 300/4L IS + 1.4x TC. As sequitur and majere have said, the 100-400IS and the Sigma 50-500 are also alternatives.

dude if you read properly, his signature says it's a sigma lens

anyway if going to singapore bird park, a 300mm at f/8 and a speedlight is more than sufficient.
